VPHONOGRAPH.

I SPECIFICATION forming part of Letters Patent No. 678,174, dated July9, 1901.

Application filed March 26, 1901. Serial No. 52,906. (No model.)

To ctZZ whom it may con/067 72;:

Be it known that I, JOHN R. HARE, of the city of Baltimore and State ofMaryland, have invented certain Improvements in Phonographs, of whichthe following is a specification.

The object of the present invention is to protect phonograph-recordsagainst injury by handling and in transporting and storing the same; andthe said invention consists in inclosing a record in a casing,- in whichit may rotate freely, the said casing having a slot through which thestyle passes to contact with the record.

In the further description of the said invention which follows,reference is made to the accompanying drawings, forming a part hereof,and in which- Figure 1 is a top view of certain parts of a phonographembodying the present invention. Fig. 2 is an enlarged partly-sectionalside View of the record, its casing, core, and shaft. Fig. 3 is across-section taken on the dotted line A A of Fig. 2 and looking in thedirection indicated by the arrow.

Referring now to the drawings, 1 is the bed of the phonograph, and 2 theshaft of the record, one end of which is adapted to enter and be securedso as to turn with the sleeve 8, which rotates in the bearing 3.

4 is a driving-pulley on the sleeve 8, and 5 a train of gearing whichtransmits rotary movement from the sleeve 8, carrying the shaft 2, tothe feed-screw, (not shown,) which screw, as in ordinary cases, isinclosed within a sleeve 6, along which the sound-reproducer traversesand which is slotted at its under side in order that a segmental nut(not shown) may be brought into contact with the-said screw. The casingcontaining the diaphragm is denoted by 7, and the nozzle to which thehorn is attached by 9.

Referring now particularly to Figs. 2 and 3, it will be seen that therecord, which is denoted by 10, is secured to the core 11, which ispreferably of wood and which in turn is fastened to the shaft 2, andthat the whole is placed within a casing 12, having the styleslot 13,the heads 14 of which serve as bearings for the said shaft. In order toprevent the record being burst by unequal expansion of the wood andcompositionfrom which the record is made, I interpose between the coreand the record an annulus 15 of some slightlycompressible substance,such as paper.

It is necessary that the casing 12 should be held stationary when theinstrument is in operation, and to this end I preferably notch thecasing at 16, and provide some fixed part of the apparatus with a lock17, adapted to enter the said notch, as shown in Fig. 1.

From the foregoing description it will be understood that each record iscontained within a casing, from which it is unnecessary to remove it,that with the protection described'records of much greater length thanthose ordinarily used may be employed, and that the records cannot beinjured by ordinary handling.

I claim as my invention 1. In combination with a phonograph-record, anda shaft to which it is secured, a casing for the said record adapted tobe held stationary while the record is in rotation, the said casingbeing provided with a slot through which the style may pass to contactwith the surface of the record, substantially as speci fied.

2. In combination with a phonograph-record and its core, an envelopingcasing having astyle-slot, which casing is loosely supported from thesaid core, and adapted to be held stationary when the core and itsrecord are rotated, substantially as, and for the purpose specified.

JOHN R. HARE.
